ARGAND LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 321,281, dated June 30, 1885.

(No modc.)

To @ZZ when@ may concern.-

Be it known that I, Janus A. CowLEs. acitizen of the United States, residing at the city of Chicago, in the State of Illinois, have invented certain new and useful Improvements in Argand Lamp-Burners, of which the following is the specification.

This improvement relates to the raising and lowering the wick and the means for holding the wick in position,as will be hereinafter described, and particularly pointed out in the claims.

Figure l is a plan view of one wick-raising tube with wick therein. Fig. 2 is a vertical section of wiek-tnbe, wick, and such other tubes as are used in au Argand burner. Fig. 3 is a plan view of a modified forni of wickraising tube with wick therein. Fig. 4 is a vertical section of wick-tube, wick, and other tubes as are used in an Argand burner. Fig. 5 is a erosssection of Fig. 2 through line .r x. Fig. 6 is a eross-section through line yy,Fig. 4.

Similar letters of reference refer to similar parts in the different drawings.

Such parts of the lamp are shown only as will illustrate my invention.

The fount is indicated at D. 'L is the outer tube, extending around and down to the bottom of the fount. d cl are holes near lower end oi' this tube, through which oil passes to the wick. The ratchetwheel E works through hole e in tube L.

J is the housing for the ratchet-wheel.

A is the wick-raising tube, made of suitable metal. This tube has perforations around its entire circumference, and they are arranged in rows. These perforations serve a double purpose. They serve as a ratchet to engage with the ratchet-wheel to raise and lower the wick-tube. They also serve as a means for holding the wiek D in position for raising and lowering it. The ratchet-wheel E is made in the usual form, having a button on the end of the shaft to turn it with.

D represents a tube within the air-tube F, for the purpose of holding the flame-spreader R. Said spreader is provided with a eupshaped socket, R', that fits snugly within the top of tube D'. This spreader has a daring top to spread the flame and to divert the air coming up through the tube F onto the inner surface of the flame. Said spreader is vertically adjustable within the tube D', whereby the angle ot' the flame or the dedection thereof may be regulated.

As the ratcl1.et-wlicel E is turned the wiektube A is raised or lowered, and the fuuction of this wick tube is to raise or lower the wick, and in order to do this it must be attached to or fastened to this wick-tube A. The wick is placed within the tube, and within the lower end of the wick is placed the band H, which tits over the air-tube F,and facilitates the placing the wick on the ai r-tube F. The wick when in position is more or less compressed between the raising-tube A and the air-tube F,which forces the wick into the apertures or perforations a a. This holds the wick D and wick-raising tube A together, so that when the raising-tube A is raised orlowered by the ratchet-wheel the wick is invariably raised or lowered also. The band H at the base of wick also assists in forcing the wick out into the apertures or perforations a a. The leading duty of this band II is to fr cilitate theplaeing ofthe wick in position on air-tube F. In Fig. 3 isshown the wick-rais ing tube A made in corrugated form. In Fig. 4 it is shown placed in fountain D', and actuated by ratchet-wheel E, inclosed in housing J. In lieu of perforations itisiprovided with a surface of rings or corrugations made in shape, size, and form to mesh-with the teeth on ratchet-wheel. It is made of thin metal, and is corrugated on both inside and outside. It is located in the burner the same as perforated wick-raising tube A, as shown in Fig. 4. The wick is placed within this corrugated tube, and at its lower end is placed the ring H, which facilitates placing the wick in position on air-tube F. The wick enters into the.

interior corrugations b b, which prevents the sliding of the wick-raising tube ou the wick when raised or lowered, and when the wickraising tube is raised or lowered by the ratchet-wheel the wick is raised or lowered at the same time.

In this improvement no additional means are necessary to fasten the wick to the wielrraising tube than those shown either in the perforated or the corrugated tube.

By using the perforated wick-raising tube A but little special attention is necessary to place it in position when once removed, as there are several series of holes into which the ratchet-wheel can Work; and, also, the Wear in 5 this tube is greatlyreduoed, as one series of holes is not obliged to be used continuously. In the corrugated form no attention or effort is required to replace it in position,as the corrugations being annular they Will mesh with 1o the ratchet-wheel at any point of its circumference.

I claiml. In combination with an Argand lampburner, a Wick-raising tube, and means for raising and lowering the same, and apressure ring, substantially as and' for the purpose shown.
